Hello All,

I am trying to execute a java program (jar file) from a WTX 8.3 map using function JEXIT in map rule. The Java program produces 4 outputs against an input. Map execution is sometime producting 4 outputs and sometimes 2 outputs for the same input set up. Java program is thowing some exception while it is not able to produce 2 outputs.

Could you please advise if this is something to do with any specific set up in map.
Thanks,
Debnarayan

Once, I tried to run the jar file from map rule. It is inconsistent.
Then, I tried to run the jar file directly (not a command line execution of the map executable file) from command prompt and it is running consistently.
